in power driven sleds, the primary object of the invention being to provide a device of this character witliv simple and effective means whereby the propelling inea-ns for the sled are at all times retained inrcontact with the ice 'or snow over which the .vehicle travels.

mother object of the invention is to pro-l vide simple and eiectiv'e means whereby the operating or propelling elements are adapted to travel under a plurality of anti-trio tional rollers, the said rollers not only sustaining the'propelling means in contact with the surface over which the vehicle travels, but also greatly reducing the friction of the same, thereby requiring but a minimum amount of power -for propelling the vehicle. A still further object of the invent-ionis the provision of means whereby a lubricant may be fed to the anti-frictional rollers.

l/Vith the above and'other objects in view which will be more appa-rent as the description progresses, the invention resides in the novel construction and combination of parts hereinafter fully described and claimed.

The Jframes of the rear runners-2 con )rise The runner is further reinforced Il@ fi 24, and each of these bars is preferably arranged directly below and in a line with the' sides of the body 19. Centrally connected with each of the said bars is a Y-shaped member 25. The lower extremity of this memberis secured to a second longitudinally extending bar 26.

The numeral 27 designates the front mem-l ber of each of the 'rear runners, This member has -its outer portion rounded but is arranged a suitable distance above the plane of the horizontal members y'of each of the front runners 1.. The upper extremity of -of vthe said knee is secured to the 'bar 26.

The lower portion of the rounded member 27 is also connected to the under face of the vbar 26'through the medium of a suitable brace,member 30.

The rear member of the frame foreach of the runners 2 has its lower extremity slightly inclined toward the member 27 as designated v by the numeral 31. This curved extension 31 is also positioned a distance above `the plane of the horizontal members of the runners=1, and the straightenedportion 32 of the rear member has .its u per, extremity bent inwardly in a substantially horizontal plane, as indicated by the numeral 33, and

this member is connected with the bar 24 in any desired manner. The inner extremity of the portion,33 is bent downwardly and has its extremity formed with a horizontal offset 34 which is secured to the upper face ofthebar26. f'f
